I tried multiple solutions for the above issue.

  1. rm -rf node_modules/ && rm -rf yarn_lock/ && yarn install && cd ios && pod install
  2. checking out the specific process & cancel thatthread/process by specifying the p_id nmp
  3. audit --fix

None of the above solution worked for me except this command enter image description here

After all you have to do yarn add react-native-gesture-handler react-native-reanimated react-native-screens

Close bundler & shift +cmd + k on xcode and run the app by cmd + R

I had the same issue, tried a lot but the solution is really simple. Just hit the 'i' key from the terminal and the connection occurs just fine.
